This invention relates to electrically operated` `devices fortherapeutic treatment, and one which willfoperate to simultaneouslytreat the portion of the body to which it is applied by a plurality ofdrii'erent effects thereon. n y An object of the invention 1sf toprovide a simple construction, whlch wlll produce heat, vibration, andeddy currents, for the purpose of treating the human body, to strengthenand build up the tissues, blood, etc.

Another object of the invention resides 1n providing a device of thischaracter, having a casing provided with a cover serving as a ldiaphragmof partial spherical form, for Iconvenient yapplication to t-he body ofa human being, which carries an armature on the inner central portionadapted to be magnetically operated by an electromagnet mounted withinthe casing energized by a thereof may be' interposed in the circuit withthe source of power anda lvarying heatingl effect of the device obtained1n order that mechanical vibration, eddy currents and heat `may beapplied to the human'body, for the treatment thereof.` A Y lTheinvention comprehends other objects and improvements .in the details ofconstruction and arrangement of the parts of the device, which are moreparticularly pointed out in the following description and claims,directed to the preferred embodiment of the invention, it beinunderstood, however, that various changes 1n this construction may bemade without departing from the spirit and scope of the invention asdescribed and claimed.

which is mounted a suitable insulating member 2, of annular form, forAreceiving and carryin thecoil windings 4,' a suitable iron core 5 ingpositioned 1n `the central'portion ofthe member 2, asillustrated inFigure 2 of the drawings. The openv front end n of the casing 1 receivesa ring member 6 and the diaphragm member 7 is threaded on the open endof the'casing and seated against the ring 6, in themanner illustratedlin Figure 2, the remaining portion thereofbeing of partial sphericalform, as clearly illustrated in Figures A1 and 2 of, the drawings, inorderto provide a surface for application to the body of a humanF beingto be treated, so that it will conveniently fit the configuration of thebody, in the application of treatment thereto. The central portion ofthe diaphragm member 7 carries an armature 8, of a size corresponding tothe core 5 of ythe electromagnet, which extends `into roximity thereto.

An annu ar shell 9 is mounted on the rear of the casing and supports aninsulating block 10, on whicha're mounted a plurality .of contacts '11,in circumferential relation,

concentric witlrl the stud -12, forming a centralY contact and pivotalmounting for the 'switch arm 13 and the dome shaped operating and covermember -V14:, having a beaded lower edge, as indicated at 15, formedofsplit sections, as indicated at 16, inorder that the same mayebeconvenientlyv applied and removed on the/ annular member 9, forvrotatably mounting the same thereon. A plurality of taps 17 are providedon the windings 4, which are each connected to respective hcontacts 11,on the insulating blocks 10. There is one additional contact mounted onthe block 10, in addition to the' number of taps on they winding,inorder to provide an off position for the switch arm 13,' in the manneras illustrated diagrammatically in' Figure 4, the same controlling thenumber of windings of they electromagnet interposed in a circuit withthe source of power, in a manner as illustrated by the Wiring diagram100 tter 105 ings will heat up more quickly than when the whole Windingis interposed in'circuit at one time.

A fiexible cable 18 carries wire connections 19 and 2O respectively, theWire connection 19 connecting one end of the windings 4, with one sideof a suitable source of power, while the wire 2O is connected to thecentral post 12 of the switch device, and a suitable source of power, sothat the winding 4 may be interposed in circuit, for effecting theoperation of the device.

The windings 4 are of such a character, that when current is appliedthereto, a degree of heat will be produced therein, of a desiredcharacter, for the treatment of the bod of a human being, and which iscontro able within predetermined limits by the adjustment of the switchto the various contacts controlling the number omi turns of the, winding4 interposed in the" circuit 1n a manner which can be clearlyascertained by an examination of Figure 4, so that a relatively greateror less degree of heat may be obtained for treatment purposes. At thesame time that the coil maintains a predetermined degree of heat, theoscillations of the alternating current will produce a constantlychanging magnetic field, through the'A core 5, which will operate toproduce a vibrating eifect on the diaphragm cover member 7, so that whenthe saine is applied in contact with the -hi'iinan body, mechanicalvibration will be set up on the surface of the body. In addition, theiron core 5 and the diaphragm 7 are so proportioned as to permit aconsiderable leakageof the magnetic lines of force, through thediaphragm and into the body of the patient, so that in the operation ofthe device to produce heat and mechanical vibrations of the diaphragmmember, through the use of an'alternating current, a magnetic field willbe produced about the electromagnet of an alternatin character, andwhich when applied to the 'said annular coil windings,

netic field, and for obtaining the results of the combined benecialeffects produced by heat and vibration.

What is claimed is:

1. A device of the class described comprising a casing, annular coil-windings mounted in said casing, a core mounted 1n a diaphragm membermounted on one end of said casing having an armature positioned in axialalineinent with said coil .for operation by the magnetic field producedan electric circuit with a source of alternatble for eddy currents dueto an alternating mageffecting vibration of said diaphragm.v

2. A device of the class described, coinprising electrically operatedmeans adapted to produce heat and eddy currents within the human bodydue to an alternating magnetic field, and a semi-spherical diaphragmoperable by said means for producing mechanical vibration, the heat,mechanical vibrations and eddy currents being ada ted to etlect thetreatment of the tissues o the human body when applied thereto.

^ 3. A device of( the class described, comprising electrically operatedmeans adapted to produce heat and eddy cui-rents within the human bodydue to an alternating magnetic field for treatingI the tissues in the'body, and means for simultaneously apply- `lng mechanical vibrations,controlled by the first mentioned means. y

In testimony whereof I ailx my signature.
